to avoid the hazards.
1-2. Arc Welding Hazards
Y The symbols shown below are used throughout this manual to
call attention to and identify possible hazards. When you see
the symbol, watch out, and follow the related instructions to
avoid the hazard. The safety information given below is only
a summary of the more complete safety information found in
the Safety Standards listed in Section 1-4. Read and follow all
Safety Standards.
D If earth grounding of the workpiece is required, ground it directly
with a separate cable.
Y Only qualified persons should install, operate, maintain, and
repair this unit.
D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
Y During operation, keep everybody, especially children, away.
D Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomatic or automatic wire welding, the
wire, wire reel, drive roll housing, and all metal parts touching the
welding wire are electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
D Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
D Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
D Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
D Do not connect more than one electrode or work cable to any
single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of
input power on inverters.
D Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
D Do not touch live electrical parts.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
D Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
D Use AC output ONLY if required for the welding process.
D If AC output is required, use remote output control if present on
unit.
D Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
D Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
D Keep your head out of the fumes. Do not breathe the fumes.
D Always verify the supply ground – check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
D When making input connections, attach proper grounding conductor first – double-check connections.
D Frequently inspect input power cord for damage or bare wiring –
replace cord immediately if damaged – bare wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or poorly spliced cables.
D Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not drape cables over your body.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
D If inside, ventilate the area and/or use exhaust at the arc to remove
welding fumes and gases.
D If ventilation is poor, use an approved air-supplied respirator.
D Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breathing air is safe.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and if necessary, while wearing an
air-supplied respirator. The coatings and any metals containing
these elements can give off toxic fumes if welded.
OM-358 Page 1
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
D Wear a welding helmet fitted with a proper shade of filter to protect
your face and eyes when welding or watching (see ANSI Z49.1
and Z87.1 listed in Safety Standards).
D Wear approved safety glasses with side shields under your
helmet.
D Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
D Wear protective clothing made from durable, flame-resistant material (leather and wool) and foot protection.
BUILDUP OF GAS can injure or kill.
D Shut off shielding gas supply when not in use.
D Always ventilate confined spaces or use
approved air-supplied respirator.
HOT PARTS can cause severe burns.
D Do not touch hot parts bare handed.
D Allow cooling period before working on gun or
torch.
MAGNETIC FIELDS can affect pacemakers.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
D Protect yourself and others from flying sparks and hot metal.
D Do not weld where flying sparks can strike flammable material.
D Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
D Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
D Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
D Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
D Do not use welder to thaw frozen pipes.
D Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
D Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
D Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
FLYING METAL can injure eyes.
D Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
D Wear approved safety glasses with side
shields even under your welding helmet.
OM-358 Page 2
D Pacemaker wearers keep away.
D Wearers should consult their doctor before
going near arc welding, gouging, or spot
welding operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
D Wear approved ear protection if noise level is
high.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding
process, be sure to treat them carefully.
D Protect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs.
D Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
D Keep cylinders away from any welding or other electrical circuits.
D Never drape a welding torch over a gas cylinder.
D Never allow a welding electrode to touch any cylinder.
D Never weld on a pressurized cylinder – explosion will result.
D Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and
associated parts in good condition.
D Turn face away from valve outlet when opening cylinder valve.
D Keep protective cap in place over valve except when cylinder is in
use or connected for use.
D Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.

1-5. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:
OM-358 Page 4
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from operator as practical.
5. Connect work clamp to workpiece as close to the weld as possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

1-5. Information sur les champs électromagnétiques
Données sur le soudage électrique et les effets des champs magnétiques basse fréquence sur l’organisme
En parcourant les câbles de soudage, le courant crée des champs électromagnétiques. Les effets potentiels de tels champs restent
préoccupants. Cependant, après avoir examiné plus de 500 études qui
ont été faites pendant une période de recherche de 17 ans, un comité
de spécialistes du National Research Council a conclu : « L’accumulation de preuves n’a pas démontré que l’exposition aux champs
magnétiques et aux champs électriques à haute fréquence constitue un
risque pour la santé humaine ». Toutefois, les études et l’examen des
preuves se poursuivent. En attendant les conclusions finales de la recherche, il serait souhaitable de réduire l’exposition aux champs
électromagnétiques pendant le soudage ou le coupage.
OM-358 Page 8
Afin de réduire les champs électromagnétiques en milieu de travail, respecter les consignes suivantes :
1. Garder les câbles ensemble en les torsadant ou en les fixant avec du
ruban adhésif.
2. Mettre tous les câbles du côté opposé à l’opérateur.
3. Ne pas s’enrouler les câbles autour du corps.
4. Garder le poste de soudage et les câbles le plus loin possible de soi.
5. Placer la pince de masse le plus près possible de la zone de soudage.
Consignes relatives aux stimulateurs cardiaques :
Les personnes qui portent un stimulateur cardiaque doivent avant tout
consulter leur médecin. Si ce dernier les déclare aptes, il leur est recommandé de respecter les consignes ci-dessus.

3-6. Weld Output Terminals And Selecting Cable Sizes*
Y ARC WELDING can cause Electromagnetic Interference.
To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor.
Locate welding operation 100 meters from any sensitive electronic equipment. Be sure this welding machine is installed
and grounded according to this manual. If interference still occurs, the user must take extra measures such as moving
the welding machine, using shielded cables, using line filters, or shielding the work area.

Definitions Of Inputs And Outputs
Inputs
A - Closure to D starts the weld cycle. Opening the closure stops weld cycle. Durning 2T operation, a momentary closure (greater than 100ms,
but less than 3/4 seconds) starts and stops weld output.
B - Closure to D turns on gas. This input will override Postflow, but if a Preflow time is entered, the Preflow cycle will time out before arc initiation.
C - Closure to D must be maintained at all times. If the closure between pins C and D is broken, an output disable occurs, Postflow begins to
time out, and HELP 13 will be displayed on the meters.
Outputs
Outputs are isolated open-collector transistors which are able to conduct 20 mA of current and 27 VDC peak.
Final Slope - output is on when in Final Slope.
Pulse Lockout - output is on when in Initial Amperage, Initial Slope, Final Slope, Final Amperage, and when the pulse frequency is less than 10
Hz.
Arc On - output is on when the contactor is on and there is less than 50 load volts.

Pulsing refers to the alternating raising and lowering of the weld output at
a specific rate. The raised portions of
the weld output are controlled in
width, height, and frequency, forming
pulses of weld output. These pulses
and the lower amperage level between them (called the background
amperage) alternately heat and cool
the molten weld puddle. The combined effect gives the operator better
control of penetration, bead width,
crowning, undercutting, and heat input. Controls can be adjusted while
welding.
Pulsing can also be used for filler material addition technique training.

filler material, or to ensure a soft
start.
INITIAL t (Initial Time)(LX Models
Only) - Press control again and turn
Encoder to select amount of time
that is needed at the beginning of
the weld.

the corresponding unit of measure
(S, %) of the active parameter will
be illuminated.
See Section 4-16 for all Adjust parameter ranges.
PREFLOW - If the TIG HF process
is active (see Section 4-7) and Preflow is shown on the control panel,
use control to set length of time gas
flows before arc initiation. To set
Preflow time for models that do not
have Preflow Time control on the
front panel, see Section 4-15.
1
Application: Preflow is used to
purge the immediate weld area of
atmosphere. Preflow also aids in
consistent arc starts.
POST FLOW - If the TIG process is
active (see Section 4-7), use control to set length of time gas flows after welding stops.
Application:
Postflow is required to cool tungsten and weld, and to prevent contamination of tungsten and weld. Increase postflow time if tungsten or
weld are dark in appearance.
DIG - If the DC Stick process is active (see Section 4-7), use control
to set amount of DIG. When set at
0, short-circuit amperage at low arc
voltage is the same as normal welding amperage.
When setting is increased, shortcircuit amperage at low arc voltage
increases.
Application:
Control helps arc starting or making
vertical or overhead welds by increasing amperage at low arc voltage, and reduces electrode sticking
while welding.

See Section 4-16 for all AC Waveshape parameter ranges.
Balance: AC Balance Control is
enabled only if AC TIG process is
selected. Use control to set percentage of time polarity is electrode
negative.
Application:
When welding on oxide forming materials such as aluminum or magnesium, excess cleaning is not necessary. To produce a good weld, only
a minimal amount, approximately a
0.10 in (2.5mm) of etched zone
along the weld toes is required.
Joint configuration, set-up, process
variables, and oxide thickness may
affect setting.
1
AC Frequency: AC Frequency
Control is enabled only if AC TIG
process is selected. Use control to
set AC frequency (cycles per second).
Application:
AC frequency controls bead width
and directional control. As AC frequency decreases, weld bead/
puddle gets wider. As AC frequency
increases, weld bead/puddle becomes narrower and the arc becomes more focused. Travel speed
can increase as AC frequency increases.

Seconds
2
1
TIG Electrode
2
Workpiece
Touch tungsten electrode to workpiece at weld start point, enable output and shielding gas with torch trigger, foot control, or hand control.
Hold electrode to workpiece for
1-2 seconds, and slowly lift electrode. Arc is formed when electrode
is lifted.
Normal open-circuit voltage is not
present before tungsten electrode
touches workpiece; only a low
sensing voltage is present between
electrode and workpiece. The
solid-state output contactor does
not energize until after electrode is
touching workpiece. This allows
electrode to touch workpiece without overheating, sticking, or getting
contaminated.
Application:
Do NOT Strike Like A Match!
Lift-Arc is used for the DCEN or AC
GTAW process when HF Start
method is not permitted, or to replace the scratch method.
HF Start
When HF Start button light is On,
start arc as follows:
High frequency turns on to help
start arc when output is enabled.
High frequency turns off when arc is
started, and turns on whenever arc
is broken to help restart arc.
Application:
HF start is used for the DCEN
GTAW process when a non-contact arc starting method is required.

10-15. Troubleshooting – Porosity
Porosity – small cavities or holes resulting from gas
pockets in weld metal.
Possible Causes
Corrective Actions
Arc length too long.
Reduce arc length.
Damp electrode.
Use dry electrode.
Workpiece dirty.
Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before
welding.
10-16. Troubleshooting – Excessive Spatter
Excessive Spatter – scattering of molten metal particles
that cool to solid form near weld bead.
Possible Causes
Corrective Actions
Amperage too high for electrode.
Decrease amperage or select larger electrode.
Arc length too long or voltage too high.
Reduce arc length or voltage.
OM-358 Page 72
10-17. Troubleshooting – Incomplete Fusion
Incomplete Fusion – failure of weld metal to fuse completely with
base metal or a preceeding weld bead.
Possible Causes
Corrective Actions
Insufficient heat input.
Increase amperage. Select larger electrode and increase amperage.
Improper welding technique.
Place stringer bead in proper location(s) at joint during welding.
Adjust work angle or widen groove to access bottom during welding.
Momentarily hold arc on groove side walls when using weaving technique.
Keep arc on leading edge of weld puddle.
Workpiece dirty.
Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before
welding.
10-18. Troubleshooting – Lack Of Penetration
Lack Of Penetration – shallow fusion between weld metal and
base metal.
Lack of Penetration
Good Penetration
Possible Causes
Corrective Actions
Improper joint preparation.
Material too thick. Joint preparation and design must provide access to bottom of groove.
Improper weld technique.
Keep arc on leading edge of weld puddle.
Insufficient heat input.
Increase amperage. Select larger electrode and increase amperage.
Reduce travel speed.
10-19. Troubleshooting – Excessive Penetration
Excessive Penetration – weld metal melting through base metal and
hanging underneath weld.
Excessive Penetration
Possible Causes
Excessive heat input.
Good Penetration
Corrective Actions
Select lower amperage. Use smaller electrode.
Increase and/or maintain steady travel speed.
OM-358 Page 73
10-20. Troubleshooting – Burn-Through
Burn-Through – weld metal melting completely through base metal resulting
in holes where no metal remains.
Possible Causes
Excessive heat input.
Corrective Actions
Select lower amperage. Use smaller electrode.
Increase and/or maintain steady travel speed.
10-21. Troubleshooting – Waviness Of Bead
Waviness Of Bead – weld metal that is not parallel and does not cover
joint formed by base metal.
Possible Causes
Unsteady hand.
Corrective Actions
Use two hands. Practice technique.
10-22. Troubleshooting – Distortion
Distortion – contraction of weld metal during welding that forces base
metal to move.
Base metal moves
in the direction of
the weld bead.
Possible Causes
Excessive heat input.
Corrective Actions
Use restraint (clamp) to hold base metal in position.
Make tack welds along joint before starting welding operation.
Select lower amperage for electrode.
Increase travel speed.
Weld in small segments and allow cooling between welds.

MILLER PRODUCTS ARE INTENDED FOR PURCHASE
AND USE BY COMMERCIAL/INDUSTRIAL USERS AND
PERSONS TRAINED AND EXPERIENCED IN THE USE

In the event of a warranty claim covered by this warranty, the

Miller. Therefore no compensation or reimbursement for
transportation costs of any kind will be allowed.
TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE FOR
DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF

ANY OTHER LEGAL THEORY.

Some states in the U.S.A. do not allow limitations of how long
an implied warranty lasts, or the exclusion of incidental,
indirect, special or consequential damages, so the above
limitation or exclusion may not apply to you. This warranty
provides specific legal rights, and other rights may be
available, but may vary from state to state.

additional warranties or remedies other than as stated herein,
